Heat To Energy New Thermoelectric Material Sets Record

August 4, 2021 | Leave a Comment

Northwestern University scientists have demonstrated a high-performing thermoelectric material in a practical form that can be used in device development. The material – purified tin selenide in polycrystalline form – outperforms the single-crystal form in converting heat to electricity, making it the most efficient thermoelectric system on record. A key application target of thermoelectric devices […]

A Simple Way to Double Thermoelectric Harvest

July 18, 2019 | Leave a Comment

Osaka University researchers applied pressure to a material to induce a Lifshitz phase transition and, in a world-first, found a direct link between the Lifshitz transition and changes in the material’s thermoelectric properties. The ability of a thermoelectric material to produce electricity from waste heat was improved more than twofold. Understanding the effect of the […]

New Thermoelectric Material Doped For High Productivity

December 1, 2015 | Leave a Comment

Northwestern University researchers are reporting that doping tin selenide with sodium boosts its performance as a thermoelectric material. The newly devised material produces a significantly greater amount of electricity than the undoped material, given the same amount of heat input. The researchers can confidently suggest the material pushes thermo electric technology closer to commercial usefulness. […]
